TABLE 4. Plant species observed at Arctomecon californica sites.

The following list includes all plant species reported to occur with Arctomecon californica. It was compiled from Nevada Natural Heritage Program records, Rancho Santa Ana Botanic Garden field research (1994), and field records supplied by Arthur Phillips. Nomenclature is from Hickman (1993) and Kartesz (1987). * indicates most frequent or characteristic associates of habitat, (A) indicates associates at Grand Canyon sites only.
